2. Good connection strength: Socket electric fusion or butt heat fusion is adopted, with few joints and no leakage.
3. Low water flow resistance: The inner surface of HDPE pipe is smooth, with low friction coefficient and large flow.
4. Good resistance to low-temperature brittleness: the brittleness temperature is (-40℃), and special protective measures are not required for construction under general low-temperature conditions (0℃).
5. Good wear resistance: The comparative test of the wear resistance of HDPE pipes and steel pipes shows that the wear resistance of HDPE pipes is 4 times that of steel pipes.
6. Strong pressure resistance: It has good impact resistance, even if there is a water hammer 2.5 times the nominal pressure, it will not cause any damage to the pipeline.
7. Anti-aging and long service life: HDPE pipes can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
